Mmm. I think the bloggers are making a mistake trying to suggest this attack has something to do with the views expressed on those blogs. From some of the information kicking about, it seems that the so-called "shadowy group" claiming responsibility is a site offering free 'sploits' for lazy h4x0r5. I.e. it would be more likely that the server was targeted in a effort to gain another zombie machine to run spamming and phishing crap from. The sploits generally work by sending various malformed URLs trying to get trough to the server 'interior' to take it over. So, it is possibly, and maybe even likely, that the attack had nothing to do with silencing anyone in particular.

And I must say, it is the responsibility of the server owner/operator to protect against script kiddies, and to keep protected backups of all material to enable recovery in case of attacks. Whining after the fact, and hoping to catch the guilty is unlikely to be very productive as sploiters are generally hosted in countries making such investigations difficult, and located all over the world.

From some info going over Dkos yesterday, it seems these sites had not spent adequate money on their programmers and server administrators to do the job done right. (In fact, it is just one guy, working half-time, and having problems getting paid promptly.) So perhaps they should look inward, rather than outward, to fix their problems, rather than assign blame.
